ObjectiveGreen Electronics = Green + ElectronicsThe word ‘green’ demonstrates the ‘ecofriendly’ character.

“ Green Electronics emphasizes on

elemination of harmful substances

& the disposal of electronic wastes ;

by applying ecofriendly techniques.”

Green Electronics is simply E-waste Management.

E-waste stands for Electronic wastes.

• HOW E-WASTES ARE GENERATED?

Hazardous substances in e-waste

Heavy metals(As,Ba ,Be,Cd,Cr,Pb,Li,Hg,Ni,Se,Zn)

Halogenated compounds PCB(Polychlorinated bi phenyles )

TBBA(Tetrabrominated-bis-phenol-A) PBB(Polybrominated di phenyl ethers)

CFC(Chloro flouro carbon )PVC(Poly vinyl chloride)

Disposal of e -waste

Basically, three techniques are used for the disposal ofE-waste materials:

1).Incineration2).Landfillng3).Recycling

incineration

Incineration involves combustion of

E-waste materials.

Volume of E-waste materials can be

Reduced upto 20-30% .

Incineration is also called as “Thermal

treatement”.

e. g. incinerators .

Land fillingSimplest & highly applicable technique .

Landfilling means “E-waste materials

are burried (filled) inside the land”.

Designing of landfills in a modern way

is a complex phenomenon.

e.g. modern landfills.

Methan Leachate treatement system gas recovery system -------------

Well to

monitor Clay trap

Ground Trash

Water

Leachate collection Aquifiersystem

recycling

Recycling refers to the widespread collection

& reuse of E-waste.

Collection of E-waste using dedicated bins,

collection vehicals.

Recycling of complex products( computer &

electronic equipments) is slightly difficult in

comparison to single type products(PVC).
